“…But, it is impossible to design a feeder with different phase shifts between the outputs in this configuration. An inclined feeder can provides certain flexibility in the choice on the phase of array [4]. Nevertheless, this last structure is bulky and does not allow designing feeder with arbitrary combination of phase and amplitude.…”

A novel single-layer power divider realised in rectangular waveguide is proposed and demonstrated. It is composed of three parts: two interdigital sub-sections and an inphase T-junction power divider. The topology can be used to design feed network having arbitrary specifications on the amplitude and phase distribution. An iterative technique is described to analyse the structure, where the divider is split into basic blocks. Large networks are then easily designed because the whole structure does not need to be simulated. Furthermore, the convergence is fast and five iterations are sufficient to obtain a variation below 0.1%. Experimental results are also presented. The 1:4 sub-section provides equal output power with 0.5 dB of insertion loss. The phase-shift between output ports is close to the specifications of -150°at 30 GHz, with an error of less than 20.

“…Coupling-slot feeders have been analyzed with the method of moments and a pattern synthesis technique was used to obtain a shaped beam broadside antenna [1]. Planar waveguide feeders have been analyzed with numerical technique including method of moment [2,3] and finite element method [4]. The synthesis is achieved by successively designing and cascading each junction [2][3][4].…”

A composite corporate traveling-wave power divider is presented. The singlelayer structure is composed of three parts: two interdigital traveling-wave subsections combined with a power splitter. An iterative design technique is described in which the divider is split into a number of basic blocks. Large-scaled networks are then easily designed because the whole structure does not need to be simulated. A method to take into account the insertion losses is also proposed and bandwidth enhancement is discussed, which is done by increasing the number of corporate layers. Experimental results are also shown for a 1:4 subsection. It provides equal output power with 0.5 dB of insertion loss. The phase-shift between output ports is close to the specifications of 21508 at 30 GHz, with an error of less than 28. It is also shown that this topology is well suited for frequency scanning antenna.

This paper presents a new wideband fixed phase shifter with substrate integrated waveguide. Inserting Air holes as a delay to create phase shift was presented before. But this paper applies from a new technique to insert the best count of Air holes and the best place of inserting Air holes. There is a direct relation between the counts of Air holes and the amount of phase shift. Two bits of phase shifts namely 15° and 30° are presented with the results of their simulation. They have 0.5° of phase ripple and their return losses and insertion losses are acceptable. These phase shifters could achieve 20% of bandwidth in KA frequency band from 32-40 GHz.Index Terms-Millimeter wave, wideband, substrate integrated waveguide, phase shifter, fixed phase, SIW
